15 should be greater than (-3w) becuase whatever you times with -3 it'll equal negative something so it's 15.
Well for THIS one you'd have to find how many miles he hikes in ONE day, so you would divide 14 by 2 to get 7 miles per day, and to find how many days he hiked in 42 miles, just divide 42 divided by 7 which equals 6, so it took him 6 days to hike 42 miles. =)
I hope I helped! =D
The answer is C, 6 x 4 = 24!
